VEHICLE WHEEL-RIM.

To all 'whom it may concern -residin at 40 Elmstrasse, Brunswick, Ger` ave invented certain new and useprovements in Vehicle Wheel-Rims, ofwhch. the following is a specification.

My invention relates to improvements in vehicle wheel rims in which a pneumatic or other resilient' tire is secured to a vehicle wheellin such a way that it can be removed man ' when. desired, as 1n case of injury, and be re laced by a perfect tire. j

ore specifically, my invention relates to that class of rims which lare constructed of two sections one of which can be removed from the felly, so that the elastic tire can be removed from or mounted'on the wheel romthe side and secured in place -by means of a clamping ring and screws.

In order to enable the screws to be tightened one or more Hat fitting rings have been interposed between the felly and the clamping ring which rings were provided with holes for the screw bolts. For adjusting the pressure of the clamping ring one or more of said flat rings'were removed and the nuts screwed down on the bolts. This construction is objectionable, because for removing the. said ring lor rings and adjusting th pressure of the clamping ring all the screw nuts must be'removed from their bolts in case the ring is located on the side of the nut-s, while all the bolts must be removed, in case the ring or rings are located l011 the side of the heads of the bolts.

The object of my improvements is to so construct the. said means for securing the rim section in place, that the pressure of the clamping ring on the rim section can be adjusted, without first removing the screw nuts-or'bolts. With this object in viewmy invention consists in composing the fitting ring or` rings of segmental sections which can be removed in a radial direction after 4slightly loosening the nuts, while they are securely held in place while the screws are ti ht ed. 5o., g en y AIn order that my invention may more clearly be understood two examples embodyingthe same have been shown in the accompanying drawing in which the same letters of reference have been used in all the views to indicate corresponding parts.

, In said drawing Figure l, is a transverse section through a tire rim and felly. Fig. 2, is a side elevation of a part of the wheel with the screw` bolts in sect-ion and the clamping ring removed, and showing the form of the fitting plates and their cut-out portions for partly embracing the bolts, Fig. 3, is a detail view shojving the said fitting plates, and Fig. {if-is a partial transverse section similar to that shownin Fig. l and illustrating a modification of the fitting plates.

Referring to the example illustrated in Figs. l to 3 of the drawing, the tire carrying rim is constructed in two sections a and a. 'lhe section a is secured to the felly (Z in any preferred way, while the section a can be laterally removed from the felly. Normally the section a .is secured in place by means of a clamping ring b and screw bolts e passing through suitable bores of the felly. One or more fitting plates c are which plates are formed with substantially radial ends abutting against one another, and which in their entity form a ring. At their outer margins the said plates bear against the screw bolts e, where they are preferably provided with eut-out portions f adapted to partly embrace the said bolts, as is most clearly shown in 3.

From the construction described it will readily be understood, that the plates are securely lheld in position, as long as the screw bolts are tightened thereon and the plates are secured within the same plane or planes. They can not be removed radially, because' they are locked by their abutting radial ends, and they can not be shifted circumferentially by reason of their friction on the felly and, in the preferred form, by reason of the cut-out portions f embracing the screw bolts. However, if it is desired to adjust the pressure of the ring Z1 the screws e are loosened sufficiently to enable the plates c to be successively displaced in the direction of the axis of the wheel and out of the plane of the other plates, whereupon the said plates can be successively removed in a radial direction. In' the preferred form several superposed fitting rings are provided by plates c. In order to further increase the reliability of the construction, IZ prefer to form the plate or plates o with projections adapted to be engaged in corresponding deinterposed between the felly and the ring f1,

" are used, each plate is lorined with a depression on one side and a corresponding elevation on the opposite side, as is clearly shown 1n Fig. 4.

'The number of the sectional plates c which form a continuous ring may be equal to the number of the screws, or a single sectional plate may be provided for several bolts, as is shown in Figs. 2 and 3.

To enable the elanii'iing ring b'to exert a strong pressure on the sectional rim a. the plates c should not he constructed broader than is necessary. Therefore the plates are so arranged as to hear with their circumference against the bolts e or to embrace the same with not more than a semicirele or less.

I claimherein as my invention:

l. In a wheel, the combination with the felly, and a rim made in annular sections,

one of which is' adapted to be nioved from saidfelly in the diret-,tion ot the axis of the I wheel, ot' clamping means, screw bolts pass:

ingr through said telly and clamping means', and fitting plates made in eonterminous sections and disposed between said clamping means andfelly, the sections of the fitting plates having their outer circumferential edgesadjacentthe inner sidesof said bolts.

2. In a wheel, the combination with the felly, and a rim made in sections one of which is adapted to be removed from said telly in the direction of the axis of the wheel, of clamping means, screw bolts passing through said lelly and clamping means, sectional tilting plates disposed between said clamping means and felly the sections of the fitting plates bein stantially semi-circular -cut-out portions. formed 1n their outer margins and'coperalive with the inner sides ot said bolts.

In a 4wheel the combination with the felly, and a`rim made in annular sections,

one of which is adapted to be removed fromv nesses.
